Journal ArticleDOI
Capillary shaping in crystal growth from melts. I. Theory
TL;DR: In this paper, the boundary conditions for the capillary equation at the shaper edge and crystal growth interfaces are discussed and analytical solutions are derived for the cases of large and small curvature liquid columns in the horizontal plane.
Journal ArticleDOI
Theoretical study of triphenylamine-based organic dyes with mono-, di-, and tri-anchoring groups for dye-sensitized solar cells
Nuha Wazzan,Ahmad Irfan +1 more
TL;DR: In this article, the effect of the number of anchoring groups on the power conversion efficiencies of three reported triphenylamine-based organic dyes with mono-, di-, and tri-substituted anchored cyanoacrylic acid group(s) on the TiO2 complexes has been explored on the frontier molecular orbitals, binding energies and absorption wavelengths.
Journal ArticleDOI
Recrystallization processes in polycrystalline silicon
C. Daey Ouwens,H. Heijligers +1 more
TL;DR: In this paper, a chemical vapor deposition technique has been used to obtain polycrystalline silicon grains of about 100 μm, which can be used as a substrate for making relatively inexpensive solar cells.
Journal ArticleDOI
Solid‐phase crystallization of Si films in contact with Al layers
J. M. Harris,R. J. Blattner,I. D. Ward,C. A. Evans,Hamish L. Fraser,M.-A. Nicolet,C. L. Ramiller +6 more
TL;DR: In this article, low-temperature (400-540 °C) crystallization of amorphous and polycrystalline Si films was studied using SEM, TEM, electron diffraction, electron channeling, and MeV 4He + backscattering.
